SPECIFICATION forming part of Letters Patent No. 592,178,dated October 19, 1897. 1

Application filed February 6,1897. Serial No. 622,274. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM A. SWEET, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Horseshoe Bars and Blanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and My invention relates to improvements in horseshoe-bars and the horseshoe-blanks produced therefrom, whereby the product is made by machinery with the greatest economy of production and the least possible waste of material, and incidentally an improved form of horseshoe results, best adapted to service and to the hygienic requirements of the animal, and one requiring the minimum of hand-labor in finishing on the part of the smith.

In the drawings forming a part of this specification, Figure 1 is a plan view of my improved bar as it comes from the rolls after the first rolling. Fig. 2 is a view in elevation of the same bar with the spaces between the calks cut out or partially so by the second step of the process, which may or may not be done by hand, portions of the bar being broken away to gain space on the drawing. Fig. 3 is a view in elevation of the bar after the portion between the calks has been reduced to the required level by a second step of rolling or other mechanical manipulation. Fig. 4 is a cross-section of the bar, approximately L- shaped, taken on the line 4 4 of Fig. 1. Fig. 5 is a cross-section of the bar, taken between the calks after secondrolling, on the line 5 5 Fig. 3. Fig. 6 is a cross-section of a modification of the bar when it is rolled for blunt calks. Fig. 7 is a cross-section of the completed shoe, taken between the calks after it has been creased by the smith and pierced Like letters of reference refer to like parts upon the several figures of the drawings.

Referring to details, a represents the body portion of the bar, which is tabular or flat along its middle part.

b represents the upright ridge at the outer margin or edge of the bar, out of which the calks are formed whencertain port-ions are cut away, as hereinafter described.

5 represents the calks left standing after the superfluous portions of the ridge have been removed.

0 represents thethinned edge of the bar, which comes innermost when the bar is curved to form the shoe-blank, and extends inward to form a base portion, its upper surface being preferably formed on a concave bevel, as

shown in crosssection, Fig. 4.

d is the narrow crease formed by the rolls or other mechanical means between the calks in second rolling.

d is the smiths crease formed by hand orotherwise in the completed blank to provide for nailing on the shoe, the nail-holes being represented in full lines in Fig. 7.

6 shows the beveled form given to the blank between the calks on the outside margin of the blank at second rolling.

The mode of procedure in forming the said product is as follows: Stock of suitable quality and dimensions for the rollingoperations is taken and passed through suitably-formed rolls to give the bar the desired form of crosssection shown in Fig. 4 or Fig. 6, a plan view of the said bar being shown in Fig. l.' The baris then cut into suitable lengths to form horseshoes, and by a subsequent operation, either by hand or by appropriate machinery for the'purpose, it is cut out on the ridge 1), between the prospective calks, as shown in Fig. 2, leaving the calks standing inplace, or, if desired, this cutting-outoperation may be performed on the bar prior to being cut into lengths. The cutting-out operation does not ordinarily extend down entirely to the tabular portion of the bar, a portion of the material of the bar being designedly, left to be reduced in the subsequent operation of second rolling, or other equiva'lent'mode of compression, which bringslthe'ba'r into the condition shown in Figs. 3 and 5. By this precaution a portion of the labor of cutting out is saved, and stock also is saved to the extent of the amount of metal capable of being rolled into the bar. During this second operation of rolling the small crease (Z is formed by a suitable provision in the rolls, or by other means, this crease being provided to form a convenient starter for the tool of the smith in putting in the final crease in the completed shoe, which provides fo attaclnnent by nails to the animals hoof. The outer side of the shoe between the calks is also beveled by suitable means, as shown at c, Fig. 5, the object being to give such a form that after creasing by the smith the bar will simply be brought back to normal proportions by the act of creasing without requiring any time-consuming and expensive hand-labor in filing, fitting, or hammering to restore it to shape and make a clean job.

The finished blank is formed in a horseshoe forming or bending machine in a well-known manner. When this blank ismade of steel of the proper quality, as is intended ,the calks can be given any temper or hardness that may be desired. The side of the finished blank which comes next the horses hoof may in practice be given a slightly-concave form to suit the predileetions of the smith.

For shoes intended for summer and fall use I make the calk-ridge of the blunt form shown in Fig. 6, but this does not essentially change the character of the bar or blank. Afterbending, the calks and the outside portion of the shoe-blank assume a slightly-convex form on the outer surface. The sharp-edged ealks are formed on the inside with the slightlycurved bevel shown in Fig. l. The length of the toe-calk may be in practice two inches or thereabout, while that of the heel-calks may be the same or somewhat less; but this is a matter fully within the discretion of the manufacturer, and the said dimensions may be increased or diminished as preferred.

I have described a horseshoe, but it is evident that the same improvements are equally applicable to muleshoes.

I claim as my invention and desire to se cure by Letters Patent- 1. A horseshoe-bar, comprising a body portion tabular or flat along its middle part, with a raised call; portion upon one side or edge thereof, the other side or edge being inclined orbeveled from the center outward to form a thinned and lightened base portion, substantially as shown and described.

2. Ahorseshoe-bar of steel suitable for tempering, comprising a body portion tabular or flat along its middle part, with a sharp raised calk portion upon one side or edge thereof, the other side or edge being thinned on a curved bevel or incline from the center of the bar outward to form a base portion, substantially as shown and described.

3. A horseshoe-bar, comprising the rolled body portion a, tabular or flat along its middle part, the upright integral ridge or calk portion Z) sharp on its upper edge and concave on its inner face, and the concave beveled base portion 0, substantially as shown and described.

A horseshoebar, comprising the body portion (t, tabular or flat along its middle part, the upright intermittent ridge portion 1), on one margin thereof, constitutingintegral heel and toe calks for use in the completed shoe, and the concavebcveled base portion 0, on the other margin thereof, substantially as shown and described.

A horseshoe-bar, com prising the flat tabular body portion a, the upright intermittent ridge portion 1), 011 one margin thereof, constituting integral heel and toe calks for usein the completed shoe, said body portion having the small crease (Z on its flat upper side between the said calks, and the thinned and beveled edge opposite the cal k-ridge, forming the base portion 0, on the other margin thereof, substantially as shown and described.

6. A horseshoe-bar of rolled metal, comprisin the flat tabular body portion a, the upright intermittent ridge portion Z), on one margin thereof, constituting integral heel and toe calks for use in the completed shoe, sharp on their upper edge and concave on their inner faee,said body portion having the small crease (l on its upperside between the said ridge portions, the bevel e on its outer edge between the calks, and the thinned and beveled inner edge with concave upper surface, forming the base portion 0, on the other margin thereof, substantially as shown and described.

7. A horseshoe-blank, comprising a curved flat:- tabular body portion, integral heel and toe calks constituting an intermittent ridge on the outer margin of the said body portion, and the inwardly-extending base portion on the inner margin of the blank, substantially as shown and described.

8. A horseshoe-blank of"; steel capable of receivin g a temper, comprising a curved flat tabular body portion, integral heel and toe ealks constituting an intermittent ridge on the outer margin of the said body portion, sharp on the upper edge and concave on the inner face thereof, a crease on the upper surface of the said body portion,near the outer margin thereof between the calks, a bevel e on the outer margin of the said body portion between the calks, and an inwardly-extending base portion having a curved beveled upper surface, forming the inner margin of the shoe-blank, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
